![]() Due for completion in 2001 this will establish digital coverage in about 1,600 1:25,000 scale sheets. A project was started in 1992 with Norwegian technical aid, to compile updated 1:25,000 scale digital coverage of these areas, derived directly from photogrammetric data. The basic scale for Irian Jaya was fixed at 1:100,000 while 1:25,000 coverage is used for Jawa, Bali and the Nusa Tenggara islands. Graticular sheet lines are used and the basic scale differs from island to island. Four 1:25,000 scale sheets cover the same area as a single 1:50,000 scale map, four 1:50,000 scale sheets comprise a 1:100,000 scale map, and six 1:100,000 scale sheets are required for each 1:250,000 scale quadrangle. Sheets are printed in a larger format than the older polyconic and TM-based series. An integrated program on the UTM projection, Spheroid Nasional Indonesia employs a hierarchical numbering system and was initiated in 1969. The National Base Mapping Program is carried out jointly by BAKOSURTANAL and the Army Topographic Directorate. ![]() This transformation has been achieved by a sustained state investment in mapping programs, and has benefited from many different bilateral aid arrangements. ![]() In the last 30 years substantial progress has been made towards the creation of an integrated and modern mapping infrastructure for the whole of Indonesia, as a necessary underpinning for economic development. Topographic maps had been prepared by the Army Topographic Service, (now Direktorat Topografi (DIOTOP)), using the polyconic projection, with series published at 1:50,000, 1:100,000 and 1:250,000 scales, but coverage of the different islands was very patchy and for many areas preliminary colonial Dutch maps, or American wartime surveys remained the best available data. Prior to 1969 there was no systematic national civilian mapping program. ![]() It is currently responsible for official geodetic, aeronautical and photogrammetric surveying, mapping and charting and acts as the national advisory and coordinating body for all surveying and mapping activities in the country. The National Coordinating Body for Survey and Mapping ( Badan Koordinasi Survey dan Pemetaan Nasional (BAKOSURTANAL)) was founded in 1969 at the start of the first five-year Indonesian development plan. ![]()
